  • Patent number: 5555606
    Abstract: A paper fastener for holding one or more sheets of paper without penetrating or damaging the paper comprises a generally channel-sectioned component having a base and opposed upper and lower arms between which the paper is received. The lower arm forms a support surface for the paper while the upper arm serves as or is provided with a gripping member to engage paper received between the arms and to bias the paper against the lower arm. At one end of the fastener the arms diverge away from each other to define an open mouth which facilitates the introduction of paper into the fastener.

  • Patent number: 5102252
    Abstract: A binder comprises suspension bars, each defining a channel with apertures leading into the channel adjacent the ends thereof. Flexible support elements are threaded through holes in sheets of paper to be received in the binder so that the paper is carried upon the elements. The channel in each suspension bar is formed and dimensioned so as to releasably retain the ends of each element therein without the need for separate retaining means. The binder is assembled by passing the ends of the elements through the apertures and pushing them into the channel where they are held in place.
